调整音频平移

Question

我正在创建一个可在两个外部屏幕上播放的视频播放器。对于两个屏幕，左侧和右侧屏幕都有一个按钮。对于每个屏幕，我想分别向左和向右平移音频。我已将此添加到我的btnRightPlay中，但音频仍然无法在右侧通道上播放。有没有人对此提出建议？我需要添加缓冲区吗？

Pan.Right.Equals(10000);

视频播放器的播放器代码

    public PlayerAvi()
    {
        InitializeComponent();
        player.stretchToFit = true;
        player.uiMode = "none";
    }


    public override bool LoadVideo(string filePath)
    {
        _path = filePath;

        player.URL = _path;
        player.Ctlcontrols.stop();

        player.settings.balance = -100;
        waveOutSetVolume(0, 0x0000FFFF);
        return true;
    }


    public override bool PlayVideo()
    {
        player.Ctlcontrols.play();
        return true;
    }

    public override bool StopVideo()
    {
        player.Ctlcontrols.stop();
        return true;
    }

    public override bool PauseVideo()
    {
        player.Ctlcontrols.pause();
        return true;
    }

    public override bool ResumeVideo()
    {
        player.Ctlcontrols.play();
        return true;
    }


    public override bool ClearVideo()
    {
        StopVideo();
        _path = null;
        return true;
    }
}
